Minarelli 2-Stroke 70cc Big Bore Kit 10mm Pin

Is your scooter to slow? That's what I thought! This big bore kit will solve the problem of loosing speed going up hills, give you about twice the acceleration power, and even give you a higher top speed. You can't go wrong upgrading your engine to 70cc. One important detail you must know is your stock scooter has a 50cc oil pump installed on it from the factory. This pumps 2-stroke oil into your engine automatically as you ride. When installing a 70cc big bore kit, you must add about a tablespoon (about a cap full from your 2t oil bottle) of oil when you fill your gas up. This will insure your now 70cc engine is getting the proper oil amount. This kit will work on all Jog/Minarelli (or 40QMB engines. This number can be found on the left side of the engine case) 2-stroke engines with a 10mm piston pin. If you are unsure what you have, let us know your model in the comment section at check out. Also, don't forget, when putting a larger cylinder on your scooter, to up-jet your carburetor
